The invention relates to a balun antenna of a printing plate. A circuit structure is realized by firstly adopting a coupling microstrip line; the structure of the balun antenna enables the temperature insensitivity of a resistor to be enhanced, the adaptability is good, and the stability is high; meanwhile, one of the advantages of the balun antenna disclosed by the invention is that the design of the balun antenna does not need other analyses and antenna simulation, and the balun antenna can be widely applied to a system needing a frequency-band antenna.
Description
Technical field
The present invention relates to antenna circuit, particularly a kind of Ba Lun antenna.Belong to RF application.
Background technology
Along with the development of the systems such as microwave and millimeter wave communication, radar, the especially development of mobile hand-held wireless communication terminal, individual soldier's satellite mobile communication terminal, military and civilian multimode multiplex communication terminal, harsh all the more to the requirement of antenna in system.Wherein, a lot of antenna causes entire system performance to worsen due to system, and terminal development speed was once slowed down.In recent years, domestic and international many researchers put forth effort to address this problem, and propose a series of solution, as transmission line radio circuit, have promoted the development of antenna to a certain extent.But in current proposed method, shortcoming is more, as designed complexity, frequency range is single, signal attenuation is comparatively large, temperature sensitivity is large.
Summary of the invention
The object of the invention is to provide a kind of utilization to be realized by low-loss coupled transfer wire material, a kind of antenna that its structure is simple, stabilized susceptibility is little, processing is simple, volume is little, stability is high.
The technical scheme realizing the object of the invention is: comprise input port (Port1) and output port (Port2), output port (Port3); Antenna utilizes low-loss coupled transmission line CT1, CT2 to form; Wherein 1 end of coupled transmission line CT1 is connected with input port 1, and 2 ends of coupled transmission line CT1 are connected with its 3 end; 4 ends of coupled transmission line CT1 are connected with 1 end of coupled transmission line CT2; 5 ends of coupled transmission line CT1 are connected with output port (Port2), and 6 ends of coupled transmission line CT1 are connected with 3 ends of coupled transmission line CT2; 2 ends of coupled transmission line CT2 are connected with output port (Port3), and 5 ends of coupled transmission line CT2 are connected with its 6 end; The 4 end open circuits of coupled transmission line CT2; Input port (Port1) and output port (Port2), output port (Port3) all connects 50 ohmages.
Compared with prior art, because the present invention adopts low-loss coupled microstrip line to realize.The remarkable advantage brought is: (1) only need consider the microstrip line material of antenna, does not need other to analyze and antenna modeling, simplicity of design; (2) temperature sensitivity is low; (3) volume is little; (4) stability is high; (5) applicability is extensive, is applicable in the various radio system higher to performance requirement.
